pc-ble-driver communication issue

Question

Hello,

I am trying to establish communication between Win 10 PC and nRF52 Dev Kit using pc-ble-driver. I followed the instructions in:

https://github.com/NordicSemiconductor/pc-ble-driver/blob/master/Installation.md

I successfully programmed the IC using the following commands:

$ nrfjprog -f NRF5<x> -e
$ nrfjprog -f NRF5<x> --program hex/sd_api_v<x>/connectivity_<ver>_<baudrate>_with_s13<v>_<a>.<b>.<c>.hex

Then I am not sure how to make the hear_rate_monitor run on the IC from Windows 10. Instruction is not clear. I flashed ble_app_hrs_pca10040_s132.hex from 14.2 SDK using nrfgo Studio and connected the device on Win 10.

Then I ran the node ../examples/heart_rate_monitor.js and got the follow error:
